Carey's publicist toldET exclusively, "Mariah and James had a fight in Greece, and have not seen each other since. The fight was not because of any cheating allegations or excessive spending by Mariah. James is one of the most successful businessmen in the world. They are trying to work it out. Right now, they’re not sure if they will stay together. They are discussing it, and plan to release an official statement together about their future."
